when using Demorgan's Theorem i didn't understand why it had to be used as logic gates AND or OR?. e.g. not x and y not x or not y in other words when facing a situation with 2 logic gates the same you make them the opposite of each other to get the answer?

i know that there are 2 fundmental ways of cryptography asymeteric and symeteric is there any formulas for cryptography? i know its for a encryption system, but there must be formulas? thanks

thats it, yea I am still practicing the equations. i thought Y2 were that if you had Y = 5 then Y2. Then to find Y2 we multiply the 5 by in this case Y2 to get 25 as Y2 would be 25 then mutliply 3N2 by the 25 to get 75 + 4 to get 79 is that ok?:smile:

2 questions 1.can a quadratic function be just set to 1 number e.g. 5 or can it be a bigger number. at the moment I am working on numbers below 10 to get used to the formulas. 2. is this correct how i am doing it? formula N --> N2--> 3N2 + 4 e.g. N =5 5 x 5 = 25 = N2...

so your saying c is not a constant in an universal equation, but can be used for other uses?

i thought a vector was a small section of the whole. but i don't think that is the case. In the book it says a 3 dimensional space vector of x = x,y,z. So space is 3d? so time is a 1 dimensional element? add those together get 4d? but i thought we cannot see the 4th dimension? or am i missing...

i read a book on quantium theory, it states that a vector of x = x,y,z. When i think about 3 dimensional space, we cannot see that, is that correct?

There are certain types of flammable liquids which cannot be put out by water easily, i know of one, rocket fuel. but there are certain like components which make the fire worse? what are they? components which like when added with water make it worse.

when there are 2 black holes and 1 is smaller than the other and they move toward each other. what would the effect be? would they combine and become 1 big black hole or would the smaller black hole just disappear?

Time I believe time is a universal inverience, whereby time doesn't stop, you can't force time to stop. We can use time in mathematics e.g. measure time to reach a certain distance. Time can be precise if properly calculated. As far as Time travel, well its theorectical and that we cannot go...

anyone know any theories being used for fluid dynamics? any formulas? I aint no physicist, I am just curious. Are there any developments today involving jet propulsion by going faster with only half the fuel? if that sounds right. any help would be appreciated

I've recently brought a physics book, and in it are some questions, which go throughout different chapters. at the moment i am on Newton's first law of motion. I looked at one of the questions on it and it asks " Explain how a car can skid on a icy road?" I remember reading in the...

to work out a traingle side e.g. 52 is it we first times the 3 by itself to get 9 and then we times the 4 x 4 to get 16. then we take away the difference to get 52? 9 + 16 = 25 Formula 32 + 42 = 52 is this correct?

I've got Geforce 4 128MB graphics card and i was astonished on what it can do. I played Star Trek Elite force yesterday and the graphics on that is amazing. I had a old voodoo 4 before, very old card, only with 32MB and its ****. I was going to get a voodoo 5 but decided to get a top end good...
